Enterprise Announces Long Term Transportation Agreements To Anchor Mid-America Pipeline Expansion.

HOUSTON -- Enterprise Products Partners L.P. (NYSE:EPD) announced today that its subsidiary, Mid-America Pipeline Company LLC ("Mid-America") has executed new long-term transportation agreements with all but one of its current shippers on the Rocky Mountain Pipeline System pursuant to the terms and conditions of Mid-America's open season tariff that was accepted by the Federal Energy Regulatory Commission ("FERC") to be effective as of August 6, 2006. Under the terms of the agreements, shippers have committed to transport all of their current and future natural gas liquids ("NGLs") production from the Rockies through Mid-America to either the Hobbs fractionator or to Mont Belvieu, Texas via the Seminole pipeline system for a minimum of 10 years and up to a maximum of 20 years. One of the shipper transportation agreements is subject to further ratification by such shipper's executive management. Based upon shipper production forecasts and current NGL extraction rates, Mid-America Pipeline expects that its current pipeline capacity of 225,000 barrels per day and its expansion capacity of 50,000 barrels per day will be fully utilized.

In December 2005, Enterprise announced a project to expand the transportation capacity of Mid-America's Rocky Mountain pipeline system by 50,000 barrels per day to facilitate the increase in production of NGLs in the Rocky Mountain area. Construction of the expansion project commenced in the second quarter of 2006 and is expected to be completed in phases through mid-2007. The expansion project will add 30,000 barrels per day of capacity by the end of 2006 from pipeline looping, and an additional 20,000 barrels per day of capacity will be added as a result of horsepower upgrades from the construction of new pump stations that are expected to be completed in mid-2007.

Last year Enterprise announced two fractionation projects downstream of the pipeline expansion that were also designed to accommodate increased production of NGLs out of the Rockies. Combined, the two projects will increase the Partnership's fractionation capacity by a total of 90,000 barrels per day. The first project, completed in April 2006, added 15,000 barrels per day of capacity to the existing NGL fractionator at Mont Belvieu, Texas. The second project, to be completed in the third quarter of 2007, is the construction of a 75,000 barrel per day NGL fractionator and related storage facilities at the interconnection of the Mid-America Pipeline and the Seminole Pipeline systems at Enterprise's Hobbs location near the border of Texas and New Mexico.

"We are pleased by the response of our shippers during the recent open season for expansion capacity on the Mid-America Rocky Mountain pipeline system. These shipper dedications highlight the attractiveness of the Mid-America pipeline system as an efficient and cost effective transporter of growing NGL production out of the Rockies to consuming markets," stated Robert G. Phillips, Enterprise President and Chief Executive Officer. "The long term agreements will anchor our current expansion and positions the Mid-America Rocky Mountain system for further expansions in the future as drilling activity in the Rockies continues."
